SPECIFICATION forming part of Letters latent No. 656,767, dated August 28, 1900.

Application filed April 5, 1900. Serial No. 11,640. (No model.)

To aZZ whom it may concern: 7 Be it known that I, CHARLES DODGE, a citizen of the United States, residing at Davis ville, county of Yolo, State of California, have invented an Improvement in Baling-Presses; andI hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in baling-presses of that class in which the follower moves in a vertically-disposed box or chamber and in which a door has its lower edge hinged near the bottom, so that the top may drop outwardly to receive the charge of material to be baled, said door being closed when the press-chamber is sufficiently filled and previous to the raising of the follower to compress the bale.

The object of my invention is to provide a means for mechanically closing the door and to allow it a free opening to receive the charge.

My invention consists of a combination of leversoperating similarly to what are known as carriage joints and connections, by which said levers are actuated to open or close the door in unison with the movements of the driving power.

My invention also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in whioh- Figure 1 is part section and part elevation of the apparatus. Fig. 2 is a front elevation. Fig. 3 is a plan. Fig. 41s a front view, and Fig. 5 a side View, of the slide.

The press-box A is of avertical type and has a follower 2, adapted to move up and down within it. \Vhen this follower is at the bottom, the press is in condition to receive the charge of material to be compressed.

As at present illustrated, the apparatus is designed for the pressing of hay, straw, and like material.

3 is a door hinged so that its upper edge can swing outwardly, leaving an opening of which it forms a side to direct the material intothe press-box. Segmental sides 4 are fixed to the press-box and extend outwardly therefrom, so that the edges of the door move between these sides and in close proximity thereto. 5 are lever-armspivoted to these opposite sides, as shown at 6, the pivot-points being below the lowest point to which the door 3 is dropped.

7 are corresponding arms pivoted to the door, as shown at 8, and the two levers 5 and 7 are hinged together at 9, so that they. may fold closely when the door is opened and so that they may be extended to stand in line with each other when the door is closed.

To the footboard 10 of the machine are hinged levers 11 which in the present case form the sides of a yoke, the ends of the levers being connected by a cross-bar at the outer end which completes the yoke, as here shown. The fulcrum-point of these levers is shown at 13, and the inner ends of the levers extend beyond the fulcrum-point, as shown.

14 is a chain one end of which is connected with a slide 20, which is movable by connection with the power apparatus, as will be hereinafter described. This chain 14 passes around a guide-pulley 15. Thence, diverging into two parts, the ends pass over the top of the yoke-lever 11 and over the bar 12 at the outer end, thence extending down and con necting with the levers 5 and 7 at their fulcrum-point 9. This fulcru m-point in the present case is represented by a shaft extending across from one to the other of the levers 5, and the levers 7 are suitably pivoted to this shaft, as plainly shown in Fig. 2.

The object of the lever 11 and the connections here shown is to raise the door 3 by pulling upon the chain 14, and turning the lever 11 about its fulcrum-point 13 it pulls upon the chain 14, where the latter extends down to the fulcrum shaft 9, and, acting through the lever or link 7, it pushes the door upwardly, the link5 turning about its fulcrum'point 6 until the door has been raised to such a point that the pivot-shaft 9 will be above the line of the fulcrum 6. When at this point the chain pulls directly upon the joint 9 and tends to straighten out the levers or links 5 and 7' until they stand in the position shown in Fig. 1, and the door 3 will then be closed. The links or levers 5 and 7 then standing in line with each other andwith the fixed fulcrumpoint6 will form a rigid brace to. retain the door in its closed position while the follower is moving up to compress the charge within the press-box. When the pull upon the chain is released, the joint 9 may be broken, as it is termed, by bending it in any appropriate manner or turned outwardly from the straight line, and the door can then be again opened about its hinges. By this construction I am enabled to open the door so fully as to allow the charge of material to be easily placed in the pressbox, and the compound movement caused by the lever 11 and the jointed links 5 and 7 provides for a sufficient are of movement of the door for that purpose.

In order to operate the device, the chain 14 leads over suitable guide-pulleys to apoint adjacent to the power apparatus from which it is actuated. In the present case this power apparatus consists of a sweep 17, which is mounted upon a vertical shaft 18, turnable in a supporting-frame. Power is applied to this sweep by means of a team of horses which, walking around in a circle, operate the sweep. I have here shown only that portion of this device which is connected with the operation of the chain let. This chain leads over a pulley 19, journaled in the horse-power frame, and connects in any suitable manner with a slide 20. This slide is here shown as formed of transverse bars separated by blocks 21 to form two open channels, one on each side of the central block. These channels fit over parallel guides 22, which are so fixed with relation to the sweep 17 that when the latter is rotated a contactpiece 23, which is fixed to the sweep, will strike the slide or an antifrict-ion-roller carried upon it and will push the slide along the guides 22, thus pulling upon the chain 14, which passes over-the pulley 19 and operating to move the lever 11 and extend the links 5 and 7 to close the door, as previously described. When by the continued movement of the sweep the contact-piece 23 is moved out of contact with the slide 20, the latter is free to be returned along the guides 22 to its normal position, and the links 5 7 and the lever 11 taking the position first de scribed the door 3 will again be opened ready for a new charge.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a balingpress and in combination with the press-box, and the hinged swinging door thereof, links having one end fulcrumed to stationary points, other links pivoted to the free ends thereof and having their opposite ends pivoted to the door, a lever fulcrumed intermediate of its ends, a chain passing over said lever to the source of power, having its outer end connected with the fulcrum-bar of the links whereby the latter is raised above the plane of the fixed pivots, and then drawn into line with the links to close the door.

2. In a baling-press, a vertical press-box, a door hinged at its lower edge, so that the upper edge swings outwardly and downwardly, segmental sides between which said door is movable, links pivoted to each of said sides, other links having one end pivoted to the door, and the others connecting with the outer ends of the first-named links, a chain connected with the fulcrum-bar of said links, a fulcrumed lever over which the outer end of said chain passes, a pulley located with'relation to the inner end of the lever and around which the chain leads to the source of power whereby the pull upon the chain first tiltsthe lever about its fulcrum, raises the hinge-joint of the links to a point above their fixed fulcrum, so that the chain can exert a direct pull upon the link-joint to bring it into the line of the links and to close the door.

3. A baling-press having a vertical press box, a doorhaving its lower edge hinged and the upper edge turnable outwardly and downwardly to open the side of the box, links pivoted respectively to fixed points and to the door and having their opposite ends pivoted together so as to fold upon eachother when the door is opened, a lever fulcrumed intermediate of its ends, a chain passing over said lever connecting with the fulcrum-joint of the links, and leading over a pulley from the inner end of the lever whereby the latter is moved to raise the links above their fixed fulcrum to allow the chain to exert a direct pull upon the joint, a slide with which the opposite end of the chain is connected, guides upon which the slide is movable, and means for applying power to move the slide and pull upon the chain.

In witness whereof I have-hereunto set my hand.

' CHARLES DODGE.
